Assume the mass ofthe rope and friction are negligible. a) Calculate the acceleration of the system. Show all work starting with free-body diagrams and net force equations for each block. b) Calculate the magnitude of the tension in the rope. Show all work. c) What would be the acceleration of the system if the tension in the ropewere equal to the weight of Block 2? Explain.in this system; a. Determine the accelerations of blocks A and B using Newton's 2nd law. b. When block B moves Im, calculate the velocities of blocks A and B using kinematic equations from the acceleration values obtained in case a. 40 kg A c. Using the conservation of energy principle, determine the velocities of blocks A and B when block B moves Im. (Neglect friction and the size of the pulley) 200 B8 kgk) Incline the track so that the block travels down it with constant velocity. Measure the inclination ("angle of repose") of the track and from this determine the coefficient of friction, How does this value of µ compare with your previous value? Pulleys: a) Consider the following problem: Suppose a 500g mass is hung from a spring scale as shown in figure 1. Predict what reading (Newtons) the spring scale will read. What force F must you exert to hold up the mass and how does this compare with the tension in the string and scale reading?

Predict what the readings will be on each of the spring scales shown in the figure. F Prediction: ni n b o 4

SA7) If the same object in SA5 and SA6 is to be placed back on top of the building where it was dropped, what will be its PE?Hi, please show full solutions and also explain how you get the answers in physics terms so it's understandable. The correct final answers are written beside too. Thank you. A slider approaches a ramp that is sloped up at an angle of 10.0º at a velocity of 6.0 m/s. The coefficient of friction between the slider and the ramp is 0.2. How far up the ramp does the slider slide? (5.0 m)This is an F=ma questions. Remember that force and acceleration are vectors. (That's what the boldface font means.) 1) A 14kg object accelerates at (2,4) m/s2. Calculate the magnitude of the force on the object, in Newtons. 2) Calculate the mass if F = (200, 300) N and a = (0.9, 0.3) m/s2. Enter 0 if there exists no answer.
